Abstract:
Methods and apparatus for stripping away portions of substrate are disclosed herein. In some embodiments, a flexible and/or soft impact-element(s) rotates around a rotation axis to drive a peripheral portion across a substrate plane of the substrate and/or to repeatedly collide with the substrate. At least some of the collisions are effective to partially dislodge or to strip away portion(s) of substrate.
Abstract:
Embodiments of the present invention relate to a system and method for manufacturing a three-dimensional object from a stack of pre-stripped layers of substrate. Each object layer is formed by (i) providing substrate comprising waste portion(s) and substrate-retained portion(s) that are attached to each other and separated from one another by cut(s) within the substrate; (ii) subsequently, subjecting the subject of each layer to a stripping process which selectively strips away substrate-waste portion(s) from the substrate-retained portion(s). After stripping, the object layer is added to a stack of previously-stacked object layers to grow the stack. This process is repeated to further grow the stack. Object layers of the stack are bonded to each other to build the three-dimensional object therefrom. Apparatus and methods for stripping are also described—any teaching or combination of teaching(s) related to stripping substrate may be employed in any additive-manufacturing process described herein.
